Classification and principle of automatic sludge dewatering machine

Jan 13, 2018

Automatic sludge dewatering machine is designed for dewatering sludge treatment equipment, it has many different categories, including plate and frame sludge dewatering machine, belt sludge dewatering machine, centrifugal sludge dewatering machine and stacked Sludge dehydrators, etc., for different types, the principle is different.


As an automatic sludge dewatering machine, the plate and frame sludge dewatering machine is in a closed state, after the high-pressure pump into the sludge through the board frame after the squeeze, so that the sludge inside the water through Filter cloth can be discharged smoothly, so as to achieve the purpose of sludge dewatering.


The belt sludge dewatering machine is not the case, it is by the upper and lower strained filter belt entrained sludge layer, from a series of regular arrangement of roller cylinder was S-shaped by the tension of the filter belt itself Form the pressing and shearing force on the sludge layer, and squeeze out some capillary water in the sludge layer to achieve the effect of sludge dewatering.


Centrifugal sludge dewatering machine is also a commonly used automatic sludge dewatering machine, which is mainly composed of screw conveyor reloader and hollow shaft, sludge from the hollow shaft to the drum, and generated at high speed rotation Centrifugal force, it will be thrown into the drum cavity.


The remaining stack of sludge dewatering machine, it is by the fixed ring, swimming ring superimposed on the composition of the formation, the screw shaft through which the formation of the filter body. This automatic sludge dewatering machine achieves the effect of sufficient dewatering by gravity concentration and an internal pressure formed by the back pressure plate during one process of sludge pushing.
